EXPLQSIVE ENGINE. APPLICATION FILED JULY 7, I919- Patent-ed Man 29, 1921.

AT'I'OR N EY S the valve momentarily opens when the piston is out or down to admit the fuel and the spark is timed to explode the fuel when the piston is up. The compression or power strokes of the piston transmit one revolution to the crank shaft and it opens the valve once to admit the fuel. The inlets 21 can be connected to a manifold and a single carburetor employed for any number of cylinders.

In the construction shown in Fig. at. the invention is applied to a multiple'four cycle engine in which the inlet and exhaust valves are operated by means of cams mounted on a secondary shaft 36 geared to the crank shaft 27 as is well known. The secondary shaft is geared to rotate half as fast as the crank shaft thereby revolving once for every two revolutions of the crank shaft. In this arrangement the induction or supply stroke would be occuring in cylinder 37, the firing stroke in cylinder 38, the compression stroke in cylinder 39 and the exhaust stroke in cyiindcr 40. The crank shaft can be geared to a counter shaft to transmit the power as is well known.

Each pair of pistons 41 are connected by a cross-head 42 to piston-rods H secured to the piston. A cOTlnQCtilig rod lf) journaled to the crosshead and fiy-wheels 29 transmits motion to the main shaft 27 by the movement of the piston. In this device the single connecting rod serves to connect two pistons to the main shaft. The upper and lower portions of the connecting rod can he furnished with ball hearings to ease up the friction and prevent play or the parts.

As shown in Fig". 5 the fuel jacket 18 wholly inc-loses a cylinder l-(S open at the top and bottom. A double acting piston 47 is arranged to reciprocate in the cylinder. Valves 48 control the intake of the fuel into the jacket. The jacket is divided into two chambers by means of a partition to admit the fuel above and below the piston. fur

exhaust port 33 in the cylinder when uncovered by the upward or downward throw of the piston discharges the products of combustion.

It will be seen that when the piston is up the products of combustion have been dis charged and the fuel charge in the upper jacket is ready to he fired. After. the e.\'- plosion the piston moves downward to compress the fuel in the lower chamber until the upper end of the piston uncovers the exhaust and in this position the fuel in the lower chamber is ready to be fired. The fuel from the carbureter is admitted into for admittin a coinlnisiihle iido 1hr in ilii.

cylinder means ior cording a compre. ion chamhci l9 and a snpph'mi ir tary piston Jill conncclml to the main i -:p-n sucks the furl through pipc ill by lLi il n ward throw. or forces the fuel llll'illlil'll pipe by its upward stroke. (heck ralvos .i l prevent backward movement of the fuel and back-firing. hence the ignition ol' lilo loci in the carburetor mixing;- chamber is pro-- vented. i
